Your answer @dumpong was a waste of time, I delete vivaldi and my associated extra data and re install the browser and started all again and nothing change, I should loggin in every page reload the extension, import bookmarks, all for nothing @dumpong@dumpong:

I agree with The_Solutor. On my windows PC, the old version I had was like that, but I did a clean install of the new snapshot and it works.
